Introduction
- The goals for transition planning and support include:
- Planning and coordinating resources in order to ensure that the specifications of the Service Design are realized.
- Starting with the transition phase, identify, manage and limit risks that could interrupt the service.
- The objectivesfor transition planning and support include:
- Plan and coordinate people and means within the frameworks.
- Make sure that everyone applies the same frameworks and standards.
- Report service issues.
- Provide clear and extensive plans.
- Support transition teams and others involved.
- Controlled planning of changes.
- Report issues, risks and other deviations.
- Scope
- The following activities are included in the scope of transition planning:
- Include design specifications and product requirements in the transition plans.
- Manage:
- Plans.
- Supporting activities.
- Transition progress.
- Changes.
- Issues.
- Risks.
- Deviations.
- Processes.
- Scope
- The following activities are included in the scope of transition planning:
- Manage:
- Supporting systems and tools.
- Monitor Service Transition achievements.
- Communicate with clients, users and stakeholders.
- Value for the business
- An integrated approach to planning improves the alignment of transition plans with the customer, service provider, business and change project plans.
- Basic concepts
- The Service Design Package(SDP) contains the following information required by the service transition team:
- Applicable service packages (e.g. core service package, service level package).
- Service specifications.
- Service models.
- Architectural design required to deliver the new of changed service including constraints.
- Definition and design of each release package.
- Detailed design of how the components will be assembled and integrated into a release package.
- Basic concepts
- The Service Design Package(SDP) contains the following information required by the service transition team:
- Release and deployment plans.
- Service acceptance criteria.
- In the release guidelines and policy, the following subjects are addressed:
- Naming conventions, distinguishing release types, such as: major release, minor release and emergency release.
- Roles and responsibilities.
- Release frequency, the expected frequency of each type of release.
- Basic concepts
- In the release guidelines and policy, the following subjects are addressed:
- Approach for accepting and grouping changes in to a release.
- How the configuration baseline for the release is captured and verified against the actual release contents e.g. hardware, software, documentation and knowledge.
- Entry and exit criteria and authority for acceptance of the release into each Service Transition stage and into the controlled test, training, disaster recovery and production environments.
- The criteria authorization for leaving Early Life Support (ELS) and handover to service operations.
Activities, methods and techniques
- The activities for planning and support consist of:
- 1.Set up transition strategy.
- 2.Prepare Service Transition.
- 3.Plan and coordinate Service Transition.
- 4.Support.
- 1.Set up transition strategy
- The transition strategy defines the overall approach to organizing Service Transition and allocating resources.
- Aspects that may be addressed in the transition strategy are:
- Purpose, goals and objectives.
- Context and scope.
- Applicable standards, agreements, legal, regulatory and contractual agreements.
- Organizations and stakeholders involved in the Service Transition.
- Framework for Service Transition.
- 1.Set up transition strategy
- Aspects that may be addressed in the transition strategy are:
- Criteria for success and failure.
- People; roles and responsibilities.
- Approach including transition model, plans for managing changes, assets, configurations and knowledge; transition estimation; preparation; evaluation; error handling; KPIs.
- The products (deliverables) that are the result of the transition activities such as transition plans, schedule milestones, financial requirements.
- 1.Set up transition strategy
- The SDP defines the various phases of the Service Transition. Theses may consist of:
- Acquiring and testing components.
- Testing service release.
- Service Operation ready test.
- Rollout.
- ELS.
- Review and close service transition.
- 2.Prepare Service Transition
- Preparatory activities consist of:
- Review and acceptance of inputs from other Service Lifecycle phases review and check the input deliverables e.g. SDP, Service Acceptance Criteria (SAC) and evaluation report.
- Identifying, raising and scheduling RFCs.
- Checking the configuration baselines are recorded in configuration management before the start of service transition.
- Checking transition readiness.
- 3.Plan and coordinate Service Transition
- A service transition plan describes the tasks and activities required to release and deploy a release into the test environments and into production including:
- Work environment and infrastructure.
- Schedule of milestones.
- Activities and tasks to be performed.
- Staffing, resource requirements, budgets and timescales at each stage.
- Lead times and contingency.
- 3.Plan and coordinate Service Transition
- Good integrated planning and management are essential to deploy a release across distributed environments and locations into production successfully.
- An integrated set of transition plans should be maintained that are linked to lower level plans such as release, build and test plans.
- It is a best practice to manage several releases in a program, with each significant deployment run as a project.
- 3.Plan and coordinate Service Transition
- Implement quality reviews for all Service Transition, release and deployment plans. Questions that might be asked are:
- Are the service transition plans and release plans up-to-date, authorized and are the release dates known?
- Were any risks related to impact on costs, organization and technology taken into account?
- Are new configuration items (Cls) compatible with each other and with configuration items in the target environment?
- Are the people who need to work with it sufficiently trained?
- Have potential changes in the business environment been taken into account?
- 4.Transition process support
- Service Transition advises and supportsall stakeholders.
- The planning and support team provide insight for the stakeholders regarding Service Transition processes and supporting and tools.
- In addition, the team will perform management/administrationof changes, work orders, issues, risks, communication and deployment.
- The team will also update stakeholders regarding planning and process.
- 4.Transition process support
- Finally, Service Transition activities are monitored:
- the implementation of activities is compared with the way they were intended (as formulated in the transition plan and model).
